Apologies to those who receive this more than once. I am completing a 
paper on polymeric substances used in the conservation, restoration and 
exhibition of fossils in museums to be given in Albuquerque in the fall, 
and I need some more anecdotal accounts. Anyone who takes a moment to 
answer the followimg questions and return them to me ASAP will receive 
my undying gratitude plus credit in the paper. I ned this by Wednesday. 
Thanks, Sally Shelton

Favorite adhesive/consolidant/hardener: (brand name, plus chemical 
compound if at all possible)

Why do you like it?

Why did you start using it?

Least favorite adhesive/consolidant/harderner (brand name, plus chemical 
compound)

Why do you dislike it?

Have you ever used an expanding foam for reconstruction? If so, what was it 
and how did you like it?

Favorite and least favorite molding compounds:

Favorite and least favorite casting compounds:

Any great anecdotes of deteriorated adhesives/consolidants/coatings that 
affected the stability and integrity of the fossils themselves?

Do you ever look up information on accelerated aging tests or other tests 
on the long-term stability of these materials before you use them?

If not, would you do so if this information was readily available?

What are three major considerations in your choice of these materials?

Any other comments/war stories/history/recommendations?

Many thanks--Sally
